Abstract

A symmetric acoustooptic time-integrating architecture able to compute the cross ambiguity function is described. An application of this new architecture is the generation of range-Doppler images from laser radar returns. This symmetric architecture has several advantages over the asymmetric time-integrating architecture, particularly in lowered optical power requirements and the elimination of background ridges. Specific advantages of the reduced optical power requirement are that (1) laser diodes are more likely to be able to satisfy the corehent optical power requirement, and (2) the risk of optical damage to the Bragg cells is diminished.
